Brian Yuzna's third of the five-part movie series is by far the best one of the entire series. While RotLD 1 + 2 were average horror flicks and RotLD 4 + 5 were on the lowest possible level, RotLD 3 is pretty convincing and worth being watched. One of the reasons are Steve Johnson's incredibly awesome SFX (he also did the SFX for A Nightmare On Elm Streeet 4 for instance). In the US, two versions were released: an R-Rated and a longer Unrated Version. There aren't many cuts in the R-Rated Version. In most cases, the R-Rated Version contains more harmless alternate takes of the violent scenes.
